Objects of the present invention are, first, to effect an economy in the construction and assembly more especially in respect to the intrcell connections; second, to improve't-he external construction and appearance of a storage battery; and third, to effect an econom; in both labor and material.

ther objects of the invention will appear from the following description and, stated broadly, the invention may be said to comprise a storage battery having its inte'rcell connections housed inside its cover or covers.

The invention also comprises the improvements to be presently described and finally 5 .claimed. v r

In the following descri tion reference will be made to the accompanying drawings formin% part hereof and in which igure 1 is a sectional elevational view "of so' much and of such parts of a storage battery as'is necessary for illustrating features of the invention in application thereto.

Fig. 2 is a top or plan view of Fig. 1 showing the same with'the cover or covers removed and with the cell. walls in section.

Fig. 3 is a top or plan view illustrating a modification.

. a'cell wall 4. It will of course be under-' Fig.7 is'a top or plan view illustratinganstood that the cell wall 4 isa part of a batter container of which the space, generally in icated at 5, is a part of a covered cell. 6 i is a plate structure housed within the interior ofa covered cell and above which there Isa gas space. As shown the part 2 of the intercell connector is a conducting button mriunted in the cell wall 4, and the part 1 of he intercell connector consists of conductmg metal such as lead alloy. The terminals 8 of the plate structures and the part 2 of the connector areequippedwith s aced con-- fronting walls rovidin betweent em chambers 9 Fig. 2,0 whicht e walls providedams useful nector by the used fluid metal or lead alloy. It may be stated that the parts 1 and 2 and the terminals-Sara in effect continuous and the demarcation shown and above re- Eerred to isset forth for the sake of explanaion. I J

Theconstruction and mode of operation of the modificationshown in Fi s. 3-6, is substantially as has been descri ed in connection with Figs. 1 and 2, except that the chamhere 10 and 11 are duplicated upon opposite side faces of each terminal '12; and these chambers 10 and 11 are of'diflferen't configuration, one, 11, being generally curved, and the other, 10, being generally rectangular to accommodate correspondingly shaped ends of a connector 13, thus insurin proper assembly in respect to the sign 0 the pole plate structures. These chambers are .filled with conducting metal which may be introduced so in a molten condition, as-by puddling or pouring. The connectors 13 are provided in spaced relation with a collar 14 and with an external thread 15, cut-into the portion 15' thereof. 16 is a nut enga ing the thread 15 and serving with the col ar 14 to clamp a cellwall 17. 18 is a soft lead washer adapted to he slipped over the thread 15'and over the ortion 15' and it is interposed between the cell wall and collar 14, and serves to pro- 00 in installing the parts 1 of the conm;

- chambers .above referred to in connection vide a tight joint. The opening provided in' the cell wall for the passage of the connector may be bounded by a continuous wall, as shown for example in Fig. 3; or it may be in the form of a notch BS] shown in Fig. 5, in which case the notchis filled with appropriate material, not shown in Fig. 5 for the sake of clearness, and adapted to provide substantial continuity of the cell wall. The cell wall may be a partition across a single container or it may be the end walls 21 and 22 of twocontainershaving inter osed between them a soft gasket 23 as of rub 7 er. This is shown in Fig. 4, and in Fig. 5 there is shown a separator 24. In Fig. 1, 25 is a sealing compound. a

The construction and mode of operation of the modification shown in Figs. 7-9 are as oi the late structure assumethe form of posts 0 which one is rectangular and the other curved and in these figures 20 are the with Figs. 1 and 2, it being understood that these chambers are filled with metal that can.

be introduced in the molten stath although it that modifications may be made in details of construction, arrangement and matters of mere form without de arting from the spirit of the inventionwhic is not limitedin respect to such matters or otherwise than as the prior' art and the appended claims may require.
